Management Commentary

“Our third quarter results reflect a transition from integration to execution with record production and Adjusted EBITDAX,” said Zack Arnold, President and CEO of Infinity. “We laid out a clear set of strategic objectives and are demonstrating our ability to execute on those objectives. We delivered meaningful growth while funding nearly all of our capital program from operating cash flow.”

“We produced strong well performance from our acquired Ohio Utica assets and completed our first deep dry gas Utica well, which remains on track to turn inline by year-end. Increased gathering utilization drove sequential declines in per-unit GP&T costs, while our acquired REX Zone 3 capacity was a competitive advantage that helped us achieve stronger pricing realizations in Ohio during the period. These are just some of the efficiencies and synergies that translated into strong Adjusted EBITDAX margins.”

“Moving forward, our focus remains on organic and strategic growth, operational efficiency and maximizing the value of our assets. With a strong balance sheet, integrated midstream infrastructure, good visibility of our cash flow through our hedging program, and a deep inventory of development opportunities, Infinity is well positioned to navigate market conditions, and deliver sustainable long-term stockholder value,” concluded Mr. Arnold.

Cautionary Statement Regarding Forward-Looking Statements

This release contains statements that express the Company’s opinions, expectations, beliefs, plans, objectives, assumptions or projections regarding future events or future results, in contrast with statements that reflect historical facts. All statements, other than statements of historical fact, included in this release regarding our strategy, future operations, financial position, estimated revenues and losses, projected costs, prospects, plans and objectives of management, future commodity prices, future production targets, leverage targets or debt repayment, hedging strategy, future capital spending plans, capital efficiency, our ability to pay future dividends and make share repurchases, expected drilling and completions plans and projected well costs, among other similar statements, are forward-looking statements. When used in this release, words such as “may,” “assume,” “forecast,” “could,” “should,” “will,” “plan,” “believe,” “anticipate,” “intend,” “estimate,” “expect,” “project,” “target,” “outlook,” “guidance,” “budget” and similar expressions are used to identify forward-looking statements, although not all forward-looking statements contain such identifying words. These forward-looking statements are based on management’s current beliefs, based on currently available information, as to the outcome and timing of future events at the time such statements were made.

Such statements are subject to a number of assumptions, risks and uncertainties, including those incident to the development, production, gathering and sale of oil, natural gas and NGLs, most of which are difficult to predict and many of which are beyond the control of the Company. These include, but are not limited to, our failure to realize, in full or at all, the anticipated benefits of capital raising transactions and acquisitions, including synergies; commodity price volatility; inflation; lack of availability and cost of drilling, completion and production equipment and services; supply chain disruption; project construction delays; environmental risks; drilling, completion and other operating risks; lack of availability or capacity of midstream gathering and transportation infrastructure; regulatory changes; the uncertainty inherent in estimating reserves and in projecting future rates of production, cash flow and access to capital; the timing of development expenditures; the concentration of the Company’s operations in the Appalachian Basin; difficult and adverse conditions in the domestic and global capital and credit markets; impacts of geopolitical events and world health events, including trade wars; the impacts of recently enacted legislation; lack of transportation and storage capacity as a result of oversupply, government regulations or other factors; potential financial losses or earnings reductions resulting from the Company’s commodity price risk management program or any inability to manage its commodity risks; failure to realize expected value creation from property acquisitions and trades; weather related risks; competition in the oil and natural gas industry; loss of production and leasehold rights due to mechanical failure or depletion of wells and the Company’s inability to re-establish production; the Company’s ability to service its indebtedness; political and economic conditions and events in foreign oil and natural gas producing countries, including embargoes, armed conflict, political instability and civil unrest, including instability in the Middle East, Venezuela and Mexico and other sustained military campaigns, the armed conflict in Ukraine and associated economic sanctions on Russia, conditions in South America, Central America, China and Russia, and acts of terrorism or sabotage; evolving cybersecurity risks such as those involving unauthorized access, denial-of-service attacks, third-party service provider failures, malicious software, data privacy breaches by employees, insiders or others with authorized access, cyber or phishing-attacks, ransomware, social engineering, physical breaches or other actions; technological advancements, including artificial intelligence and its application in our industry; risks related to the Company’s ability to expand its business, including through the recruitment and retention of qualified personnel; and the other risks described in our filings with the U.S. Securities and Exchange Commission (the “SEC”), including our most recent Annual Report on Form 10-K and any subsequent Quarterly Reports on Form 10-Q or Current Reports on Form 8-K.

Reserve engineering is a process of estimating underground accumulations of hydrocarbons that cannot be measured in an exact way. The accuracy of any reserve estimates depends on the quality of available data, the interpretation of such data and price and cost assumptions made by reserve engineers. In addition, the results of drilling, testing and production activities may justify revisions of estimates that were made previously. If significant, such revisions would change the schedule of any future production and development program. Accordingly, reserve estimates may differ significantly from the quantities of oil and natural gas that are ultimately recovered.

Please read the Company’s filings with the SEC, including “Risk Factors” in the Company’s most recent Annual Report on Form 10-K, and in other filings we make with the SEC, for a discussion of the risks and uncertainties that could cause actual results to differ from those in such forward-looking statements. As a result, actual outcomes and results could materially differ from what is expressed, implied or forecast in such statements. Therefore, these forward-looking statements are not a guarantee of our performance, and you should not place undue reliance on such statements. All forward-looking statements, expressed or implied, included in this press release are expressly qualified in their entirety by this cautionary statement. Any forward-looking statement speaks only as of the date on which such statement is made, and the Company undertakes no obligation to correct or update any forward-looking statement, whether as a result of new information, future events or otherwise, except to the extent required by law.

Non-GAAP Financial Measures

In addition to disclosing financial results calculated in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”), our earnings release contains non-GAAP financial measures as described below.

Adjusted EBITDAX, Adjusted EBITDAX Margin, Net Debt and Recurring Cash G&A We define Adjusted EBITDAX as net income (loss) plus interest, net, income tax expense (benefit), depreciation, depletion, and amortization, unrealized loss (gain) on derivative instruments, net cash settlements received (paid) on derivatives, non-cash compensation expense and non-recurring transaction expenses. We believe Adjusted EBITDAX is useful because it makes for an easier comparison of our operating performance, without regard to our financing methods, corporate form or capital structure. We determined our adjustments from net income (loss) to arrive at Adjusted EBITDAX to reflect the substantial variance in practice from company to company within our industry depending upon accounting methods and book values of assets, capital structures, and the method by which the assets were acquired. Adjusted EBITDAX should not be considered more meaningful than or as an alternative to net income (loss) determined in accordance with U.S. GAAP. Certain items excluded from Adjusted EBITDAX are significant components in understanding and assessing a company’s financial performance, such as a company’s cost of capital and tax burden, as well as the historic costs of depreciable assets, none of which are components of Adjusted EBITDAX. Our presentation of Adjusted EBITDAX should not be construed as an inference that our results will be unaffected by unusual or non-recurring items. Our computations of Adjusted EBITDAX may differ from and may not be comparable to similarly titled measures of other companies. Adjusted EBITDAX Margin is defined as Adjusted EBITDAX divided by total production.

Net debt is defined as total long-term debt less cash and cash equivalents. Management uses net debt to evaluate its financial position, including its ability to service its debt obligations.

Recurring Cash G&A is defined as U.S. GAAP general and administrative expense exclusive of the Company’s stock-based compensation and non-recurring transaction expenses. Recurring Cash G&A per Mcfe is defined as Recurring Cash G&A divided by total production for a period. These metrics are used by management because they isolate cash costs within G&A expense and measure cash costs relative to overall production, which is a widely utilized metric to evaluate operational performance within the energy sector. We believe Recurring Cash G&A and Recurring Cash G&A per Mcfe provide external users of the Company’s consolidated financial statements with additional information to assist in their analysis of the Company.

The following table provides a reconciliation of our net loss, the most directly comparable financial measure presented in accordance with U.S. GAAP, to Adjusted EBITDAX for the periods presented herein:

(1) Consists primarily of fees and expenses related to the Antero Acquisition in 2026 and one-time, non‑cash stock‑based compensation associated with the Company’s IPO in 2025.

The following table provides a reconciliation of total debt, the most directly comparable financial measure presented in accordance with U.S. GAAP, to net debt:

(1) Includes $61.2 million of borrowings to fund a short-term deposit associated with the Antero Acquisition as of December 31, 2025.

The following table provides a reconciliation of general and administrative expense, the most directly comparable financial measure presented in accordance with U.S. GAAP, to Recurring Cash G&A:

(1) Consists primarily of fees and expenses related to the Antero Acquisition in 2026 and one-time, non‑cash stock‑based compensation associated with the Company’s IPO in 2025.
